How to use ReadXML to Extract Supervisor Information

Hi,

I am new to use ReadXML in C#.  I have partial code below which will read the XML data from XDocument then import them into SQL dataset.  I use XDocSupv.CreateReader method to convert XML format into dataset rows.  For some reason, I ran into multiple supervisor rows of Linda Lambert in the dataset and missing some of the rows that they should be in.  In the attached XML sample file, I have a James Davis and Susan Wong report to Linda Lambert who is the supervisor.  Notice that each employee has a supervisor field toward the end of each employee record.  Now, I get multiple rows Linda Lambert in my dataset.  I am expecting one row of each employee James, Susan, and Linda on the dataset result.  It looks like the supervisor at the end of each employee is overriding the employee.  Is there another way to write the ReadXML to read XDocument then parse it into dataset?

How should I change my dsSupv.ReadXML(XDocSupv.CreateReader()) to extract the XML file correctly?

Any suggestion would be appreciated.
